Problem Solved
Enterprises manage sprawling application inventories with massive redundancies, high license run-rates, and technical debt, lacking a structured methodology to decide which systems to retire, migrate, or modernize.
When to Use
- •Conducting an enterprise-wide cloud migration assessment across hundreds of on-premises applications
- •Eliminating redundant SaaS and custom tools post-merger or during technology cost optimization programs
- •Scoring applications along Business Value vs Technical Health to populate a Gartner TIME quadrant
When NOT to Use
- •For deep single-monolith architecture refactoring blueprints (use TPL-TRN-009)
- •For general corporate IT asset inventories and serial number registers (use TPL-OPS-003)
5 Template Sections & Structural Outline
Cataloging all enterprise systems with business ownership, primary user base, SLA tiers, and technology stacks.
Objective scoring across 10 business dimensions (revenue generation, regulatory criticality) and 10 technical dimensions (code health, cloud readiness, security).
Applying deterministic rule trees to classify each application into the optimal modernization or disposition strategy.
Modeling upfront migration CapEx against annual run-rate OpEx savings across infrastructure, software licenses, and support labor.
Grouping applications into logical migration clusters based on database dependencies and business domain alignment.

Application Portfolio Rationalization and 6R Disposition Workbook - Worked Case Study
Fictional Entity: Pinnacle Logistics Global — 420-Application Enterprise Portfolio ($55M Cloud Modernization)
Real-world production case study demonstrating complete operational adoption for Pinnacle Logistics Global — 420-Application Enterprise Portfolio ($55M Cloud Modernization).
- •Evaluated 420 applications: classified 72 for immediate Retirement, 45 for Repurchase (SaaS), 140 for Rehost/Replatform, and 55 for deep Refactoring
- •Targeted the retirement of 72 redundant tools, releasing $12.4M in annual licensing and maintenance cash flow
- •Constructed a 5-wave, 24-month cloud migration roadmap reducing total infrastructure footprint by 42%
Frequently Asked Questions
What is the fundamental difference between Replatforming and Refactoring in the 6R model?
Replatforming ("lift, tinker, and shift") modifies core infrastructure components (e.g. migrating an on-premises Oracle database to managed AWS Aurora) without altering the application code or core architecture. Refactoring fundamentally redesigns the code and architecture into cloud-native microservices or serverless functions to unlock elasticity and scalability.
Why should enterprises aggressively seek "Retire" candidates early in portfolio rationalization?
Retiring unused or redundant systems costs zero cloud migration CapEx while immediately eliminating licensing, server hosting, and security patching overhead. The realized savings fund subsequent complex refactoring waves.
How does the Gartner TIME model map to the AWS 6R strategies?
Tolerate aligns with Retain; Invest aligns with Refactor/Rearchitect; Migrate aligns with Rehost/Replatform; Eliminate aligns with Retire and Repurchase (replacing bespoke code with commodity SaaS).
